Equating these two time scales implies (rho^{-1/2}propto T^{1-alpha }), where (alphasimeq4) is the power-law exponent of the cooling function.
The method reported in this paper is a simple means by which to determine the Avrami exponent, n, after cooling from the molten state of semi-crystalline polymers.
The genre's best-known American exponent was William M. Harnett, a cool-handed virtuoso.
Regardless of the composition, the value of the Avrami exponent is 2.8 3.5, depending on the cooling rate, whereas the value of the Ozawa exponent is 2.1 2.6, depending on the temperature.
It is demonstrated that the mean interface spacing of the Ti 46.5at.%Al 4at.% (Cr, Nb, Ta -B alloy decreases wiTa -Bcrealloy cooling rate following an exponential expression with an exponent of −0.39.
There are strong dependences of the degree of crystallinity (Xc), peak crystallisation temperature (Tp), half time of crystallisation (t1/2), and Ozawa exponent (m) on the SiO2 content and cooling rate.
Crystallization upon cooling, reduced cold crystallization temperature, increased spherulite density and lower Avrami exponent values for branched PLAs in comparison to linear one suggest enhanced nucleation process as a result of a branched chain architecture.
"It's being published for Father's Day," says this exponent of what one critic referred to as "the chilled-out cool", with a suspiciously uncool smile.
The value of Avrami exponent n for HDPE/POSS (90 10) nanocomposite ranged from 2.5 to 2.9 and decreased with increasing cooling rate.
The Avrami exponent n is found to change for pure Al as well as for Al 0.3Ti 0.02B alloy with cooling rate and the rate constant k decreases by an order of magnitude for Al 0.3Ti 0.02B alloy compared to pure Al.
